Deployment for ARM (AWS EC2 t4g)

I am trying to upgrade my EC2 instances, but it is not building the image. I am very inexperienced in this field, so I don't know what is the issue. Is it the docker image, the meteor build command (where there is the architecture parameter) or something else? It is a new instance and the config is tailored for that, but I believe the config itself should be fine.

Mup version (mup --version): 1.5.1

Mup config

{
  "servers": {
    "one": {
      "host": "1.2.3.4",
      "username": "ubuntu",
      "pem": "~/.ssh/pem"
    }
  },
  "proxy": {
    "domains": "sifty.pigmonitor.cz",
    "ssl": {
      "letsEncryptEmail": "tosinek@gmail.com",
      "forceSSL": true
    }
  },
  "app": {
    "name": "my-app",
    "path": "../",
    "servers": {
      "one": {}
    },
    "buildOptions": {
      "debug": true,
      "serverOnly": true
    },
    "env": {
      "ROOT_URL": "https://subdomain.host.com",
      "MONGO_URL": "mongodb://subdomain.subdomain.host.com:27017/db",
    },
    "docker": {
      "image": "abernix/meteord:node-12-base",
      "prepareBundle": true,
      "useBuildKit": true,
    },
    "enableUploadProgressBar": true,
    "deployCheckWaitTime": 600,
  }
}
